The Internet of Things will revolutionize everything! Manufacturing? Dog walking? Coffee bean refilling? Car driving? Food eating? Put a sensor in it! The marketing makes it pretty clear that there’s no part of our lives which isn’t enhanced with The Internet of Things. Why? Because with a simple sensor and a symphony of corporate hand waving about machine learning an iPhone-style revolution is just around the corner! Enter: Amazon Dash, circa 2014.
The first product in the Dash family was actually a barcode scanning wand which was freely given to Amazon Fresh customers and designed to hang in the kitchen or magnet to the fridge. When the Fresh customer ran out of milk they could scan the carton as it was being thrown away to add it to their cart for reorder. I suspect these devices were fairly expensive, and somewhat too complex to be as frequently used as Amazon wanted (thus the extremely limited launch). Amazon’s goal here was to allow potential customers to order with an absolute minimum of friction so they can buy as much as possible. Remember the “Buy now with 1-Click” button?
That original Dash Wand was eventually upgraded to include a push button activated Alexa (barcode scanner and fridge magnet intact) and is generally available. But Amazon had pinned its hopes on a new beau. Mid 2015 Amazon introduced the Dash Replenishment Service along with a product to be it’s exemplar – the Dash Button. The Dash Button was to be the 1-Click button of the physical world. The barcode-scanning Wands require the user to remember the Wand was nearby, find a barcode, scan it, then remember to go to their cart and order the product. Too many steps, too many places to get off Mr. Bezos’ Wild Ride of Commerce. The Dash Buttons were simple! Press the button, get the labeled product shipped to a preconfigured address. Each button was purchased (for $5, with a $5 coupon) with a particular brand affinity, then configured online to purchase a specific product when pressed. In the marketing materials, happy families put them on washing machines to buy Tide, or in a kitchen cabinet to buy paper towels. Pretty clever, it really is a Buy now with 1-Click button for the physical world.
There were two versions of the Dash button. Both have the same user interface and work in fundamentally the same way. They have a single button (the software can recognize a few click patterns), a single RGB LED (‘natch), and a microphone (no, it didn’t listen to you, but we’ll come back to this). They also had a WiFi radio. Version two (silently released in 2016) added Bluetooth and completely changed the electrical innards, though to no user facing effect.
In February 2019, Amazon stopped selling the Dash Buttons. Continue reading “The Amazon Dash Button: A Retrospective”
Amazon’s Dash Buttons are useful little devices, that let you automatically order a wide variety of common household goods at the press of a button. They’re cheap and wireless and readily available, and that makes them ripe for hacking. In just this vein, [Inbar] and [Ezra] found a way to make the Dash buttons update their to-do list.
[Inbar] uses Any.do to manage his to-do list. There’s no public API, but the service can be configured to respond to Alexa commands. Naturally, this meant that if a Dash Button could be configured to trigger a voice command, Alexa would then make the necessary additions to the list.
This was achieved with lashings of Python, a Raspberry Pi, and Apple’s text-to-speech engine. The Raspberry Pi is set up as a wireless hotspot, to which the Dash Buttons are connected. When the button is pressed, a DHCP request goes out as the button tries to phone home. By scraping the MAC address from this request, the Raspberry Pi can identify which button has been pressed, and then plays a recorded voice sample of Apple’s Samantha voice. This voice was specifically chosen to be the one most reliably understood by Alexa, which is responsible for parsing the voice command and updating the list on Any.do.
It’s a cheeky hack that doesn’t bother itself with the nitty-gritty of interfacing with various services and tools. Instead, it laces up a bunch of easy-to-use software and hardware, and gets the job done just as well.
As we’ve seen, Amazon’s Dash Button has been thoroughly pwned. Video after the break. Continue reading “Making A Dash Button Update Your To-do List”
If you haven’t heard about the Amazon dash button yet we’re glad you quit watching cat videos and have joined us. Just to get you up to speed: the Amazon dash button is a small wireless device that lets your lazy ass order more laundry soap by pushing the “dash button” which should be affixed to something near your washing machine. The pushing of the button will set in motion the gut wrenching process that we used to know as “buying things we ran out of” but thanks to Amazon we can now just cover our entire lives with an assortment of buttons that take zero credentials to physically push. We can’t see that being a problem whatsoever.
Needless to say we as a community set out to find an actual use for these fantastic little devices. [maximus64] has done quite a nice job at enabling this hardware in a most usable way. Most of the hacks we have seen for the dash button remove the physical push button and add a sensor of some kind. Replacing the button with a sensor still uses the WiFi connection to send data from the button to the cloud. Instead of the button ordering more <<product>> from Amazon, a sensor might trigger the dash to increment a counter on your website letting you know that your dog went through the doggy door +1 more times.
[maximus64] has the dash button working in the reverse manner by porting the Broadcom IoT WICED SDK to the button. He is using the dash button as a receiver and when [maximus64] sends the “all good” signal from his laptop to the dash button his garage door opens which you can see in the video after the break. We find this extremely more useful than the dash button’s original intended use. [maximus64] has instructions in the readme.md file of the github repo so that you too can hack your dash button in this way.

The Amazon Dash is a $5 push-to-buy-cat-litter button which has excellent potential for repurposing, but you need to know what is going on inside first. [Tony Dicola] has the details in this excellent bare metal guide to the Dash. In this, he covers how to get inside the Dash and reprogram it to do something more interesting than buying cat litter.
He first cracks the device open, connecting a programmer, then building a toolchain to compile programs to run on. This isn’t for the faint-hearted because you are programming directly for a device that wasn’t really built for it, but [Tony] has posted examples and there are few tools to hold your hand on the way. There is a safety net, [Tony] provided details on how to reset the Amazon Dash Button if you manage to brick it.
We have seen some interesting hacks that repurpose the Dash to capture your child’s bowel movements by intercepting the device connecting to WiFi, but this guide takes it a step further. It allows you to run your own code, which turns this into a really low-cost and well-engineered all-in-one WiFi device. The missing piece is proof-of-concept code to run the WiFi module inside. If you’re working on that we’d love to hear about it!

We’re still not too sure if the Amazon Dash button is a brilliant marketing and advertising ploy, or is just downright stupid. But what we do know, is for $5, it’s a lot of hackable tech that could be used for more… useful purposes. The big A sells these dash buttons for one purpose — you push the button and whichever product is assigned to it shows up on your doorstep in a few days. [Ted Benson] wanted them to do more than that so he turned a few dash buttons into a way of tracking his baby’s health!
Apparently, data acquisition of your baby’s wake-up times and poops is useful to identify health patterns. [Ted] tried using some phone apps to keep track of this stuff, but found it would be a lot easier if there was just a big button on the wall or something… which is where he got the idea to make use of the Amazon Dash button.
It’s actually really simple to do. Buy the dash button, do the setup with Amazon… but don’t do the final step: selecting the product you want to order. If you don’t select anything, you won’t order anything…

The Amazon Dash Button is a tiny WiFi-enabled device that’s a simple button with a logo on the front. If you get the Tide-branded version, simply press the button and a bottle of laundry detergent will show up at your door in a few days. Get the Huggies-branded version, and a box of diapers will show up. Get the sugar-free Haribo gummi bear-branded version, and horrible evil will be at your doorstep shortly.
[Matt] picked up one of these Dash Buttons for 99 cents, and since a button completely dedicated to buying detergent wasn’t a priority, he decided to tear it apart.
The FCC ID reveals the Amazon Dash Button is a WiFi device, despite rumors of it having a Bluetooth radio. It’s powered by a single AA battery, and [Matt] posted pictures of the entire board.
Since this piece of Amazon electronics is being sold for 99 cents, whatever WiFi radio chip is inside the Dash Button could be used for some very interesting applications. If you have an idea of what chips are being used in [Matt]’s pictures, leave a note in the comments.
